UNITED STATES PATENT OEEIOE.

Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed MEtI'Ch 7, 1905. Serial N0. 248.794.

To all whom, it muy concern.-

Be it known that I, JAMES POWER, a citizen of the United States,residing at Methuen, in the county of Essex and State Of Massachusetts,have invented a new and useful Improvement in Sash-Locks, of which thefollowing is a specification.

This invention is an improved form of sash-lock, the Object being toprovide a simple and efficient device by means of which either the upperor lower sash can be locked in either an Open or closed position andwith this object in view the invention consists in the novel features ofconstruction hereinafter fully described, and pointed out in the claim.

In the drawings forming a part of the specification, Figure l is a viewshowing One side of a window with my improved construction of sash-lockapplied thereto. Fig. 2 is a horizontal sectional view on the line 2 2of Fig. 3. Fig. 3 is a vertical sectional view on the line 3 3 of Fig.2. Fig. 4 is a detail perspec tive view of the sleeve within which thebolt works. Fig. 5 is a view of the bolt.

Referring to the drawings, A indicates a side rail of the lower sash,and B the side rail of the upper sash, which rail has a horizontal boreor passage-way C produced therein, and the forward face of each rail isrecessed, as shown at D, said recess communicating with the horizontalbore C. A sleeve E is arranged in each horizontal bore C, the outer endof the sleeve being flanged, as shown at E, by means of which it isfastened in the rail of the sash. The opposite end of the sleeve isclosed, and this closed end preferably projects beyond the inner face ofthe side rail of the sash, as shown. Intermediate the ends of the sleeveand in the side adjacent the recess D is produced a horizontal slot E2,which slot communicates at each end with transverse slots E3. A box orcase F fits snugly in each recess D, said box having a hinged cover F',which fits Hush with the face of the side rail of the sash when closed.The back or rear wall of the box or case is slotted horizontally, asshown at F2, which slot communicates with vertical slots F3, said slotsF2 and F3 registering with the slots E2 and E3, as most clearly shown inFig. 2.

G indicates the bolt which is arranged to slide in the sleeve E, and ispreferably constructed with annular ribs G. A spiral For the purpose ofmanipulating the bolt n G, I employ a pin I, which is threaded into thebolt, said pin being passed through the slots, and is provided with ahead I', which rests within the box or casing F. When it is desired tounlock the sash, the bolt is pushed back by means of the pin and thesaid pin turned up or down in the inner slots E3 and F3, thereby holdingthe bolt in its unlocked position. When it is desired to lock thewindow, the pin is released and the Spring will force the bolt intoengagement with the first recess Or socket it is brought into alinementwith, and, if desired, the bolt can be secured in this position byturning the pin up or down in the Outer slots E3 and F3, as most clearlyshown in the lower sash of Fig. 1.

It will thus be seen that I provide an exceedingly simple and efficientconstruction of sash-lock capable of carrying out all of the objectshereinbefore referred to, and which will operate in the manner setforth.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination with a sash having a horizontal bore and a recesscommunicating with said bore, of a sleeve fitting in said recessprovided with horizontal and vertical slots communicating with eachother, a box fitting in said recess having slots formed in its rearwall, corresponding with the slots of the sleeve, a bolt provided withannular ribs arranged in said sleeves, a spring arranged at one end ofthe sleeve, a pin secured to the bolt extending through the slots of thesleeve and box, and provided with a head, and a hinged cover adapted toclose said box, for the purpose described.
